[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] In the related art, an electrolysis device is usually configured in the air purification device, and the electrolysis device is immersed in the saline solution of the water tank assembly, so as to use the electrolysis device to electrolyze the saline solution into electrolyzed water that can be used for disinfection and sterilization. When using the air purification device, the user usually puts an appropriate amount of loose salt particles into the water tank assembly and then into the water tank of the water tank assembly to form a saline solution that can be electrolyzed by the electrolysis device. However, when putting loose salt particles into the water of the water tank assembly, it is often difficult to control the amount of loose salt particles put in. If the number of salt particles put in is insufficient, the concentration of the saline solution in the water tank is insufficient, which will result in a low concentration of the electrolyzed water after electrolysis, making it difficult to achieve the effect of disinfection and sterilization.

[0038] In view of the above issues, please refer to Figures 1 to 3 The present invention provides an embodiment of a salt adding mechanism, which can be configured in an air purification device 600 to add salt to a water tank assembly 620 of the air purification device 600. The salt adding mechanism can accurately control the amount of salt added to the water tank assembly 620, thereby improving the accuracy of controlling the concentration of the salt solution.

[0039] See also Figures 3 to 5 In one embodiment of the salt adding mechanism of the present invention, the salt adding mechanism includes a base 100, a salt storage tank 200 and a distributor 300; wherein the base 100 is provided with a distributor bin 110, and the distributor bin 110 is provided with a discharge port 113; the salt storage tank 200 is installed on the base 100 to be suitable for storing salt balls 400, and the salt storage tank 200 is connected to the distributor bin 110; the distributor 300 is installed on the distributor bin 110, and the distributor 300 is movable relative to the base 100, and can discharge the salt balls 400 discharged from the salt storage tank 200 to the distributor bin 110 to the discharge port 113 in batches.

[0040] Specifically, the base 100 can have a variety of shapes and structural designs, which are not specifically limited here. For example, the base 100 can be set in a cylindrical shape, and the sub-bin 110 is set at the upper end of the base 100. Of course, in other embodiments, the base 100 can also be designed as a support frame with support legs; or, the base 100 can also be designed as a chassis.

[0041] For the salt storage tank 200, the salt storage tank 200 is suitable for storing salt balls 400 of spherical design, and these salt balls 400 are uniform in size, that is, the volume and weight of these salt balls 400 are basically the same. The salt storage tank 200 is installed on the base 100 and is located above the distribution bin 110 of the base 100. The salt balls 400 in the salt storage tank 200 are discharged downward to the distribution bin 110, and then by driving the distributor 300 to move, the salt balls falling in the distribution bin 110 can be discharged in batches to the discharge port 113, so that the salt balls are sent from the discharge port 113 to the water tank assembly 620. It should be noted here that batch discharge refers to discharging the salt balls 400 in batches, for example, each batch discharges n (n≥1) salt balls 400, and the user can choose to discharge one batch or multiple batches according to needs. Assuming that a box of water needs to dissolve one salt ball 400 to reach the ideal salt water concentration, the distributor 300 only needs to discharge one salt ball 400 to the discharge port 113 each time. If a box of water needs to dissolve three salt balls 400 to reach the ideal salt water concentration, the distributor 300 can discharge three salt balls 400 to the discharge port 113 at a time, or the distributor 300 can be divided into three batches, and each batch discharges one salt ball 400 to the discharge port 113.

[0042] As for the distributor 300, the distributor 300 is suitable for transferring and conveying salt balls 400. The salt balls 400 are different from the scattered salt particles in the normal state. The salt balls 400 are spheres integrated with a certain amount of salt particles. The diameter of the salt balls 400 is much larger than the particle size of the salt particles. Therefore, the structure of the distributor 300 should be reasonably designed according to the diameter of the salt balls 400 to meet the requirements of transferring and conveying these salt balls 400.

[0043] For example, the distributor 300 can be configured as a rotatable feeding wheel, and a feeding groove is provided around the feeding wheel, and the salt balls 400 can be transferred to the discharge port 113 by rotating the feeding wheel. For another example, the distributor 300 can also be configured as a movable ball taking spoon, and the ball taking spoon can be moved in the vertical direction or in the horizontal direction; when the ball taking spoon moves to communicate with the salt storage tank 200, the salt balls 400 in the salt storage tank 200 fall into the ball taking spoon; and when the ball taking spoon moves in the opposite direction to the discharge port 113 of the distribution bin 110, the salt balls 400 are discharged from the ball taking spoon to the discharge port 113.

[0044] In practical applications, the hypochlorous acid concentration (i.e., electrolyzed water concentration) required for the virus, bacteria, and other indices in the use environment can be calculated according to the disinfection standard requirements; then, the expected salt water concentration and electrolysis time required for electrolysis are calculated through electrolysis chemical equation conversion; then, the required amount of salt particles to be added is calculated according to the expected salt water concentration and the volume of the water tank assembly 620; finally, the salt particles equal to the amount of salt particles to be added are prepared into salt balls 400 arranged in a spherical shape. In this way, a number of salt balls 400 can be prepared, and the diameters of these salt balls 400 are basically the same, so the volumes and weights of these salt balls 400 are also basically the same. These salt balls 400 are stored in the salt storage tank 200 of the salt adding mechanism. Whenever the water tank assembly 620 is refilled with water, these salt balls 400 can be transferred one by one to the discharge port 113 through the salt adding mechanism, and then sent to the water tank assembly 620 of the air purification device 600.

[0045] It should be noted that each time the air purification device 600 refills the water tank assembly 620 with water, the salt adding mechanism can output at least one salt ball 400 to the water tank assembly 620. If the concentration of the salt solution in the water tank assembly 620 needs to be increased, the salt adding mechanism can output multiple salt balls 400 to the water tank assembly 620.

[0046] It should be noted that the salt ball 400 may be configured in the salt adding mechanism by the manufacturer before leaving the factory; or may be purchased or prepared by the user and placed in the salt adding mechanism.

[0047] The technical solution of the present invention is to install a salt storage tank 200 for storing salt balls 400 on the base 100, and connect the salt storage tank 200 with a distribution bin 110 on the base 100. A distributor 300 is arranged in the distribution bin 110. The distributor 300 is movable relative to the base 100, and can discharge the salt balls 400 flowing from the salt storage tank 200 into the distribution bin 110 to the discharge port 113 in batches, so that the number of salt balls 400 put into the water tank assembly 620 each time can be accurately controlled, and the weight of the salt balls 400 put into the water tank assembly 620 can be accurately controlled, thereby improving the accuracy of controlling the brine concentration of the water tank assembly 620.

[0048] See also Figures 4 to 6In one embodiment, the distributor 300 is provided with a plurality of distribution troughs 321 for accommodating the salt balls 400; the distributor 300 is movable relative to the base 100, and the plurality of distribution troughs 321 are connected to the discharge port 113 one by one. The salt storage tank 200 discharges the salt balls one by one into the plurality of distribution troughs 321 in the distribution bin 110, and then the distributor 300 is driven to move relative to the base 100, so that the plurality of distribution troughs 321 are connected to the discharge port 113 one by one, thereby discharging the salt balls in the plurality of distribution troughs 321 one by one through the water tank assembly 620.

[0049] Regarding the movable installation mode of the divider 300, the divider 300 can be rotatably installed in the divider bin 110, and by driving the divider 300 to rotate, the multiple divider slots 321 are connected to the discharge port 113 one by one. Alternatively, the divider 300 can also be movably installed in the divider bin 110, so that by driving the divider 300 to move, the multiple divider slots 321 are connected to the discharge port 113 one by one; for example, the divider 300 is movably installed in the divider bin 110 in the up-down direction; or the divider 300 is movably installed in the divider bin 110 in the horizontal direction.

[0050] In this embodiment, the distributor 300 is rotatably installed in the distributor bin 110; the multiple distributor grooves 321 of the distributor 300 are arranged at intervals along the circumference of the distributor 300. Specifically, assuming that the central angle between two corresponding adjacent distributor grooves 321 of the distributor 300 is θ (e.g. Figure 8 As shown); when the divider 300 rotates to the point where one of the divider slots 321 is connected to the discharge port 113, the salt balls in the divider slot 321 are discharged from the discharge port 113; and then the divider 300 is driven to rotate; when salt balls 400 need to be added, each time the divider 300 is driven to rotate through a central angle θ, it will switch to the next divider slot 321 of the divider 300 to be connected to the discharge port 113.

[0051] According to the above operation, the salt balls 400 in the plurality of the distributing troughs 321 of the distributor 300 can be output to the discharge port 113 one by one in sequence. The more the number of the distributing troughs 321, the smaller the center angle θ; conversely, the larger the center angle θ. In practical applications, it can be set according to the supply of the required salt balls, and there is no specific limitation here.

[0052] Further, the material distributor 300 includes a rotating part 310 and a plurality of partitions 320 disposed on the periphery of the rotating part 310 and connected to the rotating part 310; the material distributor 321 is formed between two adjacent partitions 320. The rotating part 310 can be rotatably connected to the base 100 or to the bottom of the salt storage tank 200. Specifically, the rotating part 310 is rotatably connected to the base 100.

[0053] See also Figure 4 , Figure 6 and Figure 7 For the salt storage tank 200, one or at least two discharge ports 211 are provided at the bottom of the salt storage tank 200, and the salt storage tank 200 is connected to the distribution bin 110 through the discharge port 211. Specifically, if the salt storage tank 200 is provided with only one discharge port 211, when the distributor 300 rotates relative to the base 100, the multiple distribution slots 321 of the distributor 300 can be sequentially connected with the discharge port 211, so that the multiple distribution slots 321 of the distributor 300 are respectively loaded with salt balls 400; and then, when the distributor 300 rotates to any one of the distribution slots 321 and is connected with the discharge port 113 of the distribution bin 110, the salt balls 400 in the distribution slot 321 roll out through the discharge port 113 of the distribution bin 110, so as to be supplied to the water tank assembly 620.

[0054] If the salt storage tank 200 is provided with a plurality of discharge ports 211, the plurality of discharge ports 211 are preferably arranged at intervals along the same circumference, and the diameter of the circumference where the plurality of discharge ports 211 are located should be consistent with the diameter of the circumference where the plurality of distribution grooves 321 of the distributor 300 are located. In this way, when the distributor 300 is rotated relative to the base 100 until its plurality of distribution grooves 321 are respectively connected with the plurality of discharge ports 211 of the salt storage tank 200 in a one-to-one correspondence, the salt balls 400 can be loaded into the plurality of distribution grooves 321 of the distributor 300 at one time; and then, when the distributor 300 is rotated until any one of the distribution grooves 321 is connected with the discharge port 113 of the distribution bin 110 in a corresponding manner, the salt balls 400 in the distribution groove 321 roll out through the discharge port 113 of the distribution bin 110, thereby being supplied to the water tank assembly 620.

[0055] See also Figure 4 , Figure 6 and Figure 7In this embodiment, the bottom of the salt storage tank 200 is provided with a plurality of discharge ports 211, and the plurality of discharge ports 211 are arranged at intervals along a circumferential region, and the spacing between any two adjacent discharge ports 211 is equal to the spacing between any two adjacent distribution grooves 321 on the distributor 300. In this configuration, when the distributor 300 rotates relative to the base 100 until its plurality of distribution grooves 321 are respectively connected with the plurality of discharge ports 211 of the salt storage tank 200 in a one-to-one correspondence, the salt balls 400 can be loaded into the plurality of distribution grooves 321 of the distributor 300 at one time; and then, when the distributor 300 rotates until any one of the distribution grooves 321 is connected with the discharge port 113 of the distribution bin 110 in a corresponding manner, the salt balls 400 in the distribution groove 321 roll out through the discharge port 113 of the distribution bin 110, and are thus supplied to the water tank assembly 620.

[0056] Furthermore, the salt storage tank 200 includes a bottom wall 210 that cooperates with the top surface of the distributor 300, and a cylindrical wall 220 arranged along the periphery of the bottom wall 210, and a plurality of discharge ports 211 are arranged on the bottom wall 210 of the salt storage tank 200 and are arranged at intervals along the circumference of the bottom wall 210.

[0057] Specifically, the bottom wall 210 and the cylinder wall 220 of the salt storage tank 200 enclose a cavity, and the cavity is used to hold the salt balls 400. After the salt storage tank 200 is installed on the base 100, the bottom wall 210 of the salt storage tank 200 cooperates with the top surface of the distributor 300, thereby covering the distribution grooves 321 of the distributor 300, and only when the distributor 300 rotates to any one of the distribution grooves 321 is below the discharge port 211 of the salt storage tank 200, the salt balls 400 in the salt storage tank 200 will fall from the discharge port 211 and be discharged into the distribution groove 321.

[0058] See also Figure 7 , Fig. 9 and Fig.10 , it is considered that the salt balls 400 may accumulate in the central area of ​​the bottom wall 210 of the salt storage tank 200 surrounded by the multiple discharge ports 211, and the salt balls 400 in this central area are not easy to be discharged from the discharge ports 211. Therefore, in order to avoid this situation, optionally, the bottom of the salt storage tank 200 is further provided with a central protrusion 212 in its central area, and the outer peripheral surface of the central protrusion 212 is arranged in an arc shape; and the multiple discharge ports 211 are arranged around the outer periphery of the central protrusion 212.

[0059] Specifically, the central protrusion 212 is disposed in the central area of ​​the bottom wall 210 of the salt storage tank 200; the central protrusion 212 is hollow, and the outer peripheral surface of the central protrusion 212 is an arc surface. By forming an arc surface on the outer peripheral surface of the central protrusion 212, the central protrusion 212 can be disposed in a spherical or hemispherical shape.

[0060] When the salt ball 400 in the salt storage tank 200 falls on the central protrusion 212, the salt ball will slide down along the arc surface in the center, so that the salt ball 400 cannot be stabilized on the central protrusion 212, and can only fall on the outer periphery of the central protrusion 212; and the outer periphery of the central protrusion 212 happens to be the discharge port 211, so the salt ball 400 sliding down from the central protrusion 212 happens to fall on the discharge port 211, so that the salt ball 400 can smoothly fall into the sub-bin 110, thereby avoiding the accumulation of salt balls 400 in the central area at the bottom of the salt storage tank 200, ensuring that as many remaining salt balls 400 as possible are discharged, and avoiding the presence of salt balls 400 that are difficult to discharge in the salt storage tank 200.

[0061] Furthermore, a guide protrusion 213 extending radially is protruding from the bottom of the salt storage tank 200, and the guide protrusion 213 is located between two adjacent discharge ports 211; the two side surfaces of the guide protrusion 213 are inclined from top to bottom toward the corresponding discharge port 211.

[0062] Specifically, the guide protrusion 213 is arranged on the bottom wall 210 of the salt storage tank 200, one end of the guide protrusion 213 is connected to the central protrusion 212, and the other end of the guide protrusion 213 extends radially to the cylinder wall 220 of the salt storage tank 200 and is connected to the cylinder wall 220. The salt balls 400 in the salt storage tank 200 are separated by the guide protrusion 213, and respectively roll down to the two side surfaces of the guide protrusion 213, and then roll down along the two side surfaces of the guide protrusion 213 to the discharge ports 211 on both sides of the guide protrusion 213, which is conducive to the discharge port 211 to discharge the salt balls 400 into the sub-bin 110, and effectively avoid the salt balls 400 staying between the two adjacent discharge ports 211, and the salt balls 400 are difficult to discharge.

[0063] Please continue reading Figure 7 , Fig. 9 and Fig.10 As for the barrel wall 220 of the salt storage tank 200, the barrel wall 220 of the salt storage tank 200 can be designed in a straight barrel shape. However, in order to ensure that the salt ball 400 falls smoothly into the discharge port 211, it is optional that at least the inner diameter of the portion where the barrel wall 220 is connected to the bottom wall 210 is gradually reduced from top to bottom.

[0064] Specifically, the barrel wall 220 of the salt storage tank 200 includes a first barrel wall 221 connected to the bottom wall 210, and a second barrel wall 222 extending upward from the upper end of the first barrel wall 221; wherein the inner diameter of the first barrel wall 221 is gradually reduced from top to bottom. This design can make the salt storage tank 200 have a funnel-shaped design. As the number of salt balls 400 in the salt storage tank 200 decreases, the remaining salt balls 400 will roll down along the first barrel wall 221 and accumulate at the discharge port 211 at the bottom of the salt storage tank 200, so that as many remaining salt balls 400 as possible can be discharged, avoiding the presence of salt balls 400 that are difficult to discharge in the salt storage tank 200. As for the shape of the second barrel wall 222, there is no specific limitation. Here, the second barrel wall 222 is arranged in a straight barrel shape so that the salt storage tank 200 has a larger volume and can store more salt balls 400.

[0065] See also Figure 4 , Figure 6 and Figure 8 Based on any of the above embodiments, the material distribution bin 110 on the base 100 includes a bin bottom 111 and a circumferential wall 112 arranged around the bin bottom 111. The material distribution bin 110 may be provided with a discharge port 113 on the bin bottom 111, or may be provided with a discharge port on the circumferential wall 112. If the discharge port 113 is provided on the bin bottom 111, the salt ball 400 may be discharged downward from the discharge port 113 under the action of its own gravity; if the discharge port 113 is provided on the circumferential wall 112, an inclined surface inclined along the outlet direction may be provided in the discharge port 113, so that the salt ball 400 may roll downward from the discharge port 113 under the action of its own gravity.

[0066] Furthermore, the salt adding mechanism also includes a feeding chute 130, which is arranged on the outside of the base 100, and the feeding chute 130 is connected to the discharge port 113 of the base 100, and the feeding channel extends downwardly obliquely from the discharge port 113. In this way, the resistance of the feeding channel to the salt ball 400 can be reduced, so that the salt ball 400 can freely roll down along the feeding channel into the water tank assembly 620 under the action of its own gravity, avoiding the salt ball 400 from staying on the feeding channel. As for the specific structural type of the feeding chute 130, the feeding chute 130 can be a straight pipe with openings at both ends; the feeding chute 130 can also be a wire trough pipe with a U-shaped cross section.

[0067] Of course, the feeding channel 130 is not necessary. In other embodiments, the sub-bin 110 can directly output the salt ball 400 to the water tank assembly 620 through its discharge port 113. For example, the salt adding mechanism is arranged above the water tank assembly 620 of the air purification device 600, so that the salt ball 400 output from the discharge port 113 of the sub-bin 110 of the salt adding mechanism directly falls downward into the water tank assembly 620. Alternatively, the salt adding mechanism is arranged on one side of the water tank assembly 620 of the air purification device 600, and the discharge port 113 of the sub-bin 110 of the salt adding mechanism is close enough to the water tank assembly 620, so that the salt ball 400 output from the discharge port 113 of the sub-bin 110 of the salt adding mechanism can also fall directly downward into the water tank assembly 620.

[0068] See also Figures 4 to 6 Based on any of the above embodiments, as for the method of driving the distributor 300 of the salt adding mechanism to rotate, a driving motor 500 may be configured for the separator to drive the distributor 300 to rotate through the driving motor 500; or, an adjusting knob may be configured for the separator to allow the user to manually drive the distributor 300 to rotate through the adjusting knob. In order to reduce user operations, optionally, the salt adding mechanism further includes a driving motor 500, the driving motor 500 is installed in the base 100, and the driving motor 500 is connected to the distributor 300 to drive the distributor 300 to rotate.

[0069] Specifically, by driving the distributor 300 to rotate automatically by the driving motor 500, the automation performance of the salt adding mechanism can be improved and the user operation can be reduced. Furthermore, by adjusting the angle of rotation of the distributor 300 by the driving motor 500, the number of salt balls 400 falling can be adjusted, thereby adjusting and increasing the concentration of the saline solution. For example, when a higher concentration of saline solution is required, the angle of rotation of the distributor 300 driven by the driving motor 500 is increased, so that the number of salt balls 400 transferred and sent by the distributor 300 can be increased, thereby increasing the concentration of the saline solution.

[0070] Furthermore, in order to facilitate the installation of the driving motor 500, a motor bin 120 located below the material distributor 110 is also provided on the base 100; the driving motor 500 is installed in the motor bin 120, and the motor shaft of the driving motor 500 passes through the motor bin 120 into the material distributor 110 and is connected to the distributor 300.

[0071] Optionally, the material distribution bin 110 and the motor bin 120 of the base 100 are arranged in an up-down direction; wherein the material distribution bin 110 is open upward; and the motor bin 120 is open downward. In this way, when assembling the salt adding mechanism, the distributor 300 can be installed into the material distribution bin 110 from the top of the base 100; and then the driving motor 500 can be installed into the motor bin 120 from the bottom of the base 100, and the motor shaft of the driving motor 500 passes through the partition plate and is connected to the rotating shaft of the distributor 300.

[0072] Based on any of the above embodiments, the salt adding mechanism also includes salt balls 400 stored in the salt storage tank 200; the maximum inner diameter of the discharge port 211 of the salt storage tank 200 is less than the sum of the diameters of any two salt balls 400, so that one discharge port 211 of the salt storage tank 200 can only supply one salt ball 400 to the distribution bin 110 at a time, thereby avoiding uneven distribution. It should be noted that the maximum inner diameter of the discharge port 113 refers to the maximum distance between any two points on the inner periphery of the discharge port 113.

[0073] See also Figure 1 and Figure 2 The present invention also provides an air purification device 600, which includes a shell 610, a water tank assembly 620 and a salt adding mechanism. The water tank assembly 620 is installed in the shell 610; the salt adding mechanism is installed in the shell 610, and the salt adding structure is used to transport salt balls 400 to the water tank assembly 620. The specific structure of the salt adding structure refers to the above embodiment. Since the present motor adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. For the air purification device 600, the air purification device 600 can be a purification device used alone, such as a disinfection machine, etc.; of course, it can also be a purification device configured inside the air conditioner.

[0074] See also Figure 1 and Figure 2 In one embodiment, the salt adding mechanism is arranged on one side of the water tank assembly 620; the salt adding mechanism includes a feeding channel 130, one end of the feeding channel 130 is connected to the discharge port 113 of the salt adding mechanism, and the other end of the feeding channel 130 extends into the water tank assembly 620. The feeding channel 130 is arranged to be inclined from top to bottom from the discharge port 113 to the water tank assembly 620, so as to reduce the resistance of the feeding channel to the salt ball 400, so that the salt ball 400 can freely roll down along the feeding channel into the water tank assembly 620 under the action of its own gravity, and avoid the salt ball 400 staying on the feeding channel.

[0075] Specifically, the water tank assembly 620 can be installed in the shell 610 in a pull-out manner; the shell 610 is provided with an installation opening for the water tank assembly 620 to be pulled out; the salt adding mechanism is installed in the shell 610 and is located on the side of the water tank assembly 620 that is away from the installation opening, so as to avoid the salt adding mechanism interfering with the water tank assembly 620 when the water tank assembly 620 is pulled out.

[0076] It is considered that sometimes after adding water to the water tank assembly 620, the user forgets to manually adjust the distributor 300 to add salt, which will result in insufficient concentration of the salt solution in the water tank assembly 620. In view of this, a sensor can also be set in the water tank assembly 620, and the sensor and the driving motor 500 of the salt adding mechanism are both connected to the controller, so that when the sensor senses that the water level of the water tank assembly 620 rises, a signal is fed back to the controller, and the controller controls the driving motor 500 to turn on according to the signal, thereby driving the distributor 300 to rotate and adding salt balls 400 to the water tank assembly 620.

[0077] In one embodiment, the water tank assembly 620 includes a water tank 621 and a water tank 622 mounted on the water tank 621, and the water tank 622 is used to supply water to the water tank 621. When the water level in the water tank 621 is lower than the upper water level, the water in the water tank 622 is discharged into the water tank 621 under atmospheric pressure, thereby storing water for the water tank 621; and when the water level in the water tank 621 is equal to or higher than the upper water level, the water tank 622 stops draining water into the water tank 621. The specific structure of the water tank 622 is relatively common in the art and is not introduced here one by one. Therefore, the "volume" of the water tank assembly 620 should refer to the initial volume of the water tank 622. Each time the water tank 622 is refilled with water, the salt adding mechanism delivers a salt ball 400 to the water tank 621.

[0078] When the salt adding mechanism is used, the required amount of salt particles to be added can be calculated in advance according to the volume of the water tank 622 and the preset salt water concentration, and then the salt particles equal to the amount of salt particles to be added are prepared into salt balls 400 arranged in a spherical shape. In this way, a number of salt balls 400 are prepared, and these salt balls 400 are basically the same in volume and weight. These salt balls 400 are stored in the salt storage tank 200 of the salt adding mechanism. Whenever the water tank 622 is refilled with water once, the salt ball 400 can be transferred to the discharge port 113 by the salt adding mechanism, and then sent to the water tank 621. It should be noted that each time the air purification device 600 refills the water tank assembly 620 with water, the salt adding mechanism can be used to output a salt ball 400 to the water tank assembly 620. If it is necessary to increase the concentration of the salt solution in the water tank assembly 620, the salt adding mechanism is used to output multiple salt balls 400 to the water tank assembly 620.

[0079] Specifically in this embodiment, each time the water tank 622 is refilled with water, the salt adding mechanism is used to output a salt ball 400 to the water tank 621. As the water in the water tank 622 is slowly injected into the water tank 621, the salt ball 400 gradually dissolves in the water tank 621 to form a salt water solution.

[0080] The technical solution of the air purification device of the present invention is to set a salt adding mechanism in its shell 610, wherein the salt adding mechanism is provided with a distributor 300 in the distribution bin 110 on the base 100, and the salt storage tank 200 for storing salt balls 400 is installed on the base 100, and the salt storage tank 200 is provided with a discharge port 211 for outputting the salt balls 400 to the distribution bin 110; the distributor 300 can rotate relative to the base 100 in the distribution bin 110, and discharge the salt balls 400 received from the discharge port 211 to the discharge port 113 in batches, thereby accurately controlling the number of salt balls 400 put into the water tank assembly 620 each time, and also accurately controlling the weight of the salt balls 400 put in, thereby improving the accuracy of controlling the concentration of the brine solution.

[0081] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
